Why walk the golf course when you can use Bubba Watson's insane jetpack instead?

Built by Martin Aircraft, BW-Air is actually an experimental aircraft capable of flying at 46 mph and at 3,000 feet of altitude. It runs on regular gasoline and makes about as much noise as a high-performance motorcycle (which means it’s pretty loud), but Thinkmodo's James Percelay insisted it's quiet — in a relative sense thanks to a piston-less rotary engine that runs at about 90 db. Its ability to take off and land vertically in relatively small spaces makes it, potentially, ideal for first responders, the actual target market. Martin Aircraft hopes to start selling to fire, police and rescue departments by then end of this year.
